I have been here for 4 nights. The room is nice and spacious, it is very clean with a nice balcony.
It is walking dostance to Silom where you have many resturants, pubs, shops etc. From the apartment you have all the facilities located on the main road: ATM, taxies, shops, etc.
For the main turistic attractions, I took a taxi, which is about 100 bath to the centre.
The landlord was very responsive to all my questions, and allowed us to leave the luggage there for 1 night while we were travelling somewhere else.
The street where the apartment is located was quite scary at the beginning, maybe because we arrived in the night.
In general is a good value for money. It is a good location if you are willing to adapt a bit.
